I only have the Quad 74 and 82 but based on this and my previous experience with the Kode 80 I would agree with Ray: Q82 is no doubt a one class bigger board ad the Q77 should feel at least as big as the K80 (which is for sure a very small 80 liter board if you go by on water feel). In fact, unless you desperately need the extra floatation a few liters more will provide, I would even say the Q74 could be an option, particularly if you're a small guy.
